Geopressured-Geothermal brines (GPGT) are an immense energy resource that remain relatively untapped throughout the world. Per U.S. Geological Survey estimates, there are 5,700 quads of recoverable gas and 11,000 quads of available thermal energy in the Gulf Coast GPGT basin alone. For comparison, the U.S. total annual energy consumption (c. 2003) is estimated at 100 quads.
